Abstract

A frameless glass door arrangement for a doorway bounded in part by a top section and a bottom section is disclosed. The frameless glass door arrangement includes two hinge parts rotatably embedded in the respective top section and bottom section; and a glass door leaf including a main body including a top edge, a bottom edge and a lateral edge, the glass door leaf further including two tongue-shaped extensions disposed adjacent to the lateral edge. The extensions extend outward from the respective top edge and bottom edge of the main body and into the respective hinge parts so that the doorway is completely transparent after the glass door leaf is installed in the doorway.

Description

• · # ··

The invention relates to a frameless glass door, in particular glass pendulum door or * cinschlagtüre with a glass door leaf in a door opening and with bottom-side and ceiling-side or side hinges. 5 Glass facades, glass walls and glass doors have gained acceptance not only in business portals but also in the area of offices and in modern interior design. They provide a clear view or perspective in both directions and contribute to the openness and the connection between inside 10 and outside. Barriers are thereby degraded and e.g. Counteracted in the business area a threshold fear.

Glass doors require fittings, especially hinges, which usually consist of metal and the bottom side and the ceiling must be flanged to the glass door leaf. 15 Metal U-profiles are used for this purpose, which overlap the hinge-side corner areas and partially enclose and hold the glass door leaf. At these metal profiles, the axes of rotation or mandrel receptacles are arranged, which engage in counterparts in the floor or ceiling construction. 20 Special training is based on a multilayer laminated glass pane. A flat piece of a hinge part engages in the composite construction, so that the glass is not as usual between two jaws of a U-profile, but surrounds the flat hinge part. A disadvantage is felt in the prior art that the glass doors are indeed frameless but yet formed with visible metallic hinge parts.

The invention aims to free the glass door leaf of all visible hinge parts and to make the entire door-30 opening invariably transparent. This is achieved in a frameless glass door of the type described above, characterized in that the glass door leaf in the region of the hinges each have tongue-like glass extensions, which protrude over the - geometric shape, in particular rectangular shape of the glass door leaf and - Outside of the field of view in the direction of the door opening into a rotating hinge part. Although this is referred to as a glass door, 5 all features apply mutatis mutandis to glass wings, such as windows. All hinge parts are thus always outside the door opening so completely in the floor or ceiling construction or completely in a door frame. The glass extensions are parts of the door leaf and make the invisible connector fertil to the invisible hinges. It is useful if the glass door leaf and the glass extensions are integrally formed. With modern adhesives, the extensions can at most attach to the glass edges. If their refractive properties correspond to the glass, 15 the splice, even if profiled for splicing, remains completely invisible. Finally, it is advantageous if the glass extensions and the hinged hinge part, e.g. are firmly connected by gluing and when the rotatable hinge part is mounted on a pin, e.g. a 20 floor door closer, can be placed. The glass extensions engage in gaps, grooves or profile recesses of the rotatable hinge part and are fixed there. These areas are entirely outside the door opening and completely out of sight. The glass extensions can engage in diagonal Nu-25 th of circular cylindrical bearing pieces, which are rotatable in rotatably mounted bearing shells, preferably between stops. Bearings and bearings may be formed as radial and axial bearings or ball bearings. Below the bottom-side or the ceiling-side 30 circular-cylindrical bearing piece, a bottom door closer can be arranged, which engages with its pin (for example square), in a corresponding recess in the bottom of the bearing piece form-fitting manner. The entire unit of non-rotating La- • • • • • • • • ♦ • ··· • · · · · I t ··· ·· - 3 - cupboard and (if present) floor - mounted door closer can be lowered down on threaded spindles (spacer screws) in a sunk mounting box so that at least one glass extension with its circular cylindrical bearing piece is released and the glass door can be removed.

Embodiments of the subject invention are illustrated in the drawings. Fig. 1 shows a frameless glass door in a door opening with the hinges in cross section, Fig. 2, the bottom hinges in plan view, Fig. 3 the 10 glass door leaf in view, Fig. 4 a corner of a door opening with glass door leaf and hinges on a floor spring partially in 5 shows another embodiment of a hinge in cross section and Fig. 6 is a section along the line VI-VI in Fig. 5. 15 According to Fig. 1, a glass door leaf 1 fills a door opening 2 shown in dashed lines in its entirety. In the door opening 2, so within the outline of the dashed line of the door opening 2 no hinge fittings or fitting parts can be seen. The glass door leaf 1, in the embodiment 20 according to Fig. 1 to 4 respectively tongue-like glass extensions 3, 4, which are provided on the narrow sides of the rectangular glass door leaf 1 next to one of the longitudinal sides. These glass extensions 3, 4 also project beyond the door opening 2, that is to say in FIG. 1 the dashed line of the door opening 2 and dip into a recess 5 of a rotatable circular-cylindrical hinge part 6, 7. These circular cylindrical hinge parts 6, 7 are bearing pieces such as bearing journals, which are rotatably received in rotatably arranged bearing shells 8, 9 corresponding to a sliding bearing. A rolling or ball bearing in the radial and / or axial direction is possible between the hinge parts 6, 7 and the rotationally fixed bearing shells 8, 9. If the latter are placed in a deeper recess • · · ································································································ Once the hinges 6, 7 are disengaged, the glass door can be unhooked.

Fig. 2 shows a plan view of the bottom hinge part 6, the recess 5 is formed as a diagonal slot or groove-5, which receives the glass extension 3 positively.

In a specific embodiment, the glass extensions had a projecting length of about 2 cm and a width of 5 to 6 cm. Considering the bottom gap of 5 mm, the depth of the recess 5 was about 1.5 cm, the length of the recess 5 was about 5 to 6 cm and the width in accordance with the thickness of the safety glass. Gluing this metal hinge part 6 with the glass extension 3 is possible.

In the manufacture of the glass door panel 1, it is assumed that there is a few (e.g., four) centimeters of overlong glass plate for 15 and then, e.g. With modern high-pressure blasting methods, the narrow side is shortened so that the glass extensions 3, 4 remain standing. The glass door leaf 1 is here formed integrally with the glass extensions 3, 4. In the embodiment according to FIG. 4, the glass extension 3 dips into a rotatable hinge part 10, which has a square recess on the bottom side. Thus, when the frameless glass door is opened, then the hinge part 10 is rotated by 75 °, for example, it clamps the bottom door closer 12 via the form-fitting attacking pin 11, which brakes correspondingly for the reverse rotation of the door Hinge parts 10 and thus ensures the closing of the glass door. The braking behavior of the floor spring as well as locking in the 90 ° position 30 can be influenced by one or more adjusting screws 13. For this purpose, a cover 14 is removable or it has closable access openings for screwdrivers or socket wrenches. ····

Fig. 4 further shows that the entire aforementioned assembly (bottom door closer 12 with pins 11) is arranged on a plate 15 which is connected by spindles, e.g. Bolt 16, 17 with hexagonal heads or Inbusausnehmungen be lowered 5 can (arrow 18). In the lowered state, the pin 11 comes back from the hinge part 10 and the glass door leaf 1 can be taken together with the hinge part 10 to the side of the door opening. For this purpose, in Fig. 4 is still the cover 14 to remove the center (in the drawing plane) ge-10 shares executed.

If the glass extensions 3 and 4 are not glued to the hinge parts 6, 7 and 10, respectively, but merely plunge into the recesses 5 positively, then by lowering all components, including the hinge part 10, the glass door leaf 1 shown in FIG. 3 are removed ,

It is also an embodiment according to FIGS. 5 and 6 possible, are provided in the glass projections 23 on a longitudinal side of the glass door leaf 24 near the bottom and near the ceiling. These glass extensions 23 project beyond the dashed line 20-marked door opening 25 and immerse each in a rotatable

Hinge part 26. The formed slot 27 and the rotation axis 28 can be seen in Fig. 6. The glass extensions 23 can be glued into the slots 27 or screws can be used, which pass through glass bores in the 25 glass extensions 23. In order to allow an opening of the glass door by 90 °, the hinge parts 26 can swing out, as illustrated by the arrow 29 in FIG. When the door is closed, the hinge part 26 completely disappears from the area of the door opening 25. The embodiment of FIGS. 5 and 6 has a rotatable hinge part 26 in the form of a cylinder with the base of a quarter-circle sector. The axis of rotation is next to the center of an imaginary full circle. When the door is closed, the hinge part 26 is completely rotatable in a form-identical recess in one. FIG door frame. When the door is opened, the hinge part 26 pivots out and allows the door to open completely through 90 °.
